You can check the Chinese air quality index for Chinese cities.
However since a few weeks this website changed...
A few weeks ago, in its old version, it provided a easy view to all Chinese cities datas.
You could simply view all the Air Quality values for all Chinese cities on one page.
Now this is not possible anymore!
This of course makes it more difficult to compile the datas and compare the values month after month.
Of course Air Quality is a sensitive subject in China. Chinese authorities are not too eager to provide such values, for instance:
- I told you that the calculation method for the air Quality differ from the international calculation method... No need to say that the Chinese calculation provides much lower values...
- Very few Chinese people wear masks or are aware of the risks, even though they are now aware of the bad air quality. The air quality is so bad that it was not possible to hide it anymore.
